ON COMBIT .. GOSUB
Summary Call up a subprogram when Bit n of the communication buffer is set.
Syntax ON COMBIT n GOSUB name
Parameter n = Bit n of communication buffer
–32 = n =32, n!= 0
name = name of subprogram
ON COMBIT refers to the first 32 Bits of the process data memory.
Description The instruction ON COMBIT is used to call up a subprogram when Bit n of the
communication buffer is set.
NB!:
– The subroutine to be called up must be defined within the SUBMAINPROG and
ENDPROG identified program.
– During the execution of an ON COMBIT subroutine NOWAIT is set to ON.
Priority If a number of interrupts occur simultaneously, the subprogram assigned to the
lowest bit is worked through first. The other interrupts will be processed after-
wards. If, during an interrupt subroutine, the same interrupt occurs (exception:
error interrupt), then it will be ignored and thus lost.
Portability In the case of COMOPTGET and COMOPTSEND, the offset of 2 Word is retained for
compatibility reasons.
Command Group INT
Cross Index SUBPROG .. RETURN, COMOPTGET, COMOPTSEND, Priorities of Interrupts, NOWAIT
Syntax Example ON COMBIT 5 GOSUB test // set interrupt on field bus bit 5
†
ON DELETE .. GOSUB
Summary Deletes a position interrupt ON APOS, ON MAPOS, or ON MCPOS
Syntax ON DELETE pos GOSUB name
Parameter pos = value
name = name of subprogram
Description The command can be used to delete an ON APOS interrupt, which is defined as
follows:
ON sign APOS xxx GOSUB name
The parameter ‘pos’ of this command can hold any value, e.g. 0. It is not checked
and has no relevance for the deletion of the interrupt. The main importance
belongs to the parameter ‘name’, which has to hold the name of the subprogram
that was formerly defined in the ON APOS command. So, the ‘ON DELETE pos
GOSUB name’ command deletes any (!) position interrupt, which belongs to the
subprogram identified by the given name. Please see sample 1.
NB!:
Only position interrupts are deleted, but no other type of interrupt.
